Full Description: The goal of the app is to help people to save lives by donating blood and bone marrow. This is because in Brazil, on average, only 1.8% of the population donates blood, when the ideal, according to WHO, would be 5%. We intend to help increase this percentage through the app, which will be made records of donors and donation requests. From the moment that a grant application is registered, the donors will be notified so they can make the donation. In addition, registered donors have the opportunity to meet the grant application, and when they do, who requested the donation receives a notice stating how many people have made themselves available to donate, thus enabling control of the number of donations achieved. The app also allows the management of donations and providing important guidelines for those who want to donate.
